WPP CEO says corporation tax “question of judgement”

WPP CEO sir Martin Sorrell has waded into the corporation tax debate on large companies, claiming the amount businesses should pay is largely a "question of judgement".

Sorrell (pictured) argued companies such as Google and Starbucks, which have come under mass criticism for their lack of corporation tax payments, will fork out for tax more out of a sense of social responsibility than because of legal liabilities, the BBC reports.

He added that "doing good is good business".

The global advertising group has relocated its headquarters back to London from Dublin following a move to Ireland in 2008 to reduce possible tax charges.

Initially, the move to Ireland was in protest at the potential "double taxation" of corporate profits proposed by the Labour government. However, the coalition dropped those plans, prompting the advertising business to come back.
